![]() ![]() Finally, wasps treated with sulfoxaflor were more likely to die in the week after treatment than wasps in the other treatment groups. ![]() Instead, wasps remained stationary and unmoving in the testing area, consistent with imidacloprid interfering with motor control. Wasps treated with high-dose imidacloprid were also less likely to complete the learning assay than wasps from the other treatment groups. Notably, both visual and olfactory performance were similarly impaired. ![]() We found that acute insecticide exposure influenced performance, as sulfoxaflor- and high-dose imidacloprid-exposed wasps made fewer correct choices than control wasps. Then, visual and olfactory learning and short-term memory were assessed. Wasps were exposed to a single, field-realistic oral dose of low-dose imidacloprid, high-dose imidacloprid or sulfoxaflor. Here, we studied the effects of an acute insecticide exposure on both olfactory and visual learning in free-moving Polistes fuscatus paper wasps. Much less is known about effects on other insect taxa or newer insecticides, such as sulfoxaflor. Thus far, much research on non-target insecticide effects has focused on neonicotinoids in a few bee species. Exposure to insecticides may contribute to global insect declines due to sublethal insecticide effects on non-target species. ![]()
